In brief, the report says the Lear 35 crashed after running out
of fuel near Aberdeen, South Dakota, more than four hours after
the last radio communication with the crew. The condition of
the wreckage made it impossible to conclusively determine what
caused the aircraft to lose cabin pressure, or why the crew
was unable to use the cockpit oxygen masks.

Some folks speculated that perhaps the Emergency Oxygen bottle
was shut off by maintenance (they apparently have a tendency to
develop slow leaks in the lines, wasting oxygen while the plane is
parked for extended periods of time) and then due to oversight not
properly turned back on. The pressure gauge reads bottle pressure
rather than line pressure and the position of the valve is not
intuitive due to the installation location and orientation. On
the other hand, if the aircrew properly checked their oxygen
equipment during preflight, the lack of pressure in the lines
should have been apparent.

If you are indeed correct about the above, and I'm sure you've done
your 'homework'; to my engineering mind - that sounds more like a
like a design oversight - scarily so even.

Requiring too many checks is a classic workload hazard. Human

Yeah right, do tell us more planespotter.

You agree with my assertion ?

p.s. btw - why do always trim the original msg the way you do ?

I've removed the sailing newsgroup from this reply - I'm sure they get
enough of your **** as it is !
